currently I have 2 PC's sharing my connection through a D-Link router - But i just purchased an iBook and now I want to go wireless aswell. What do I need to buy? Is there some sort of thing I attach to my current router, or can I just hook up a new wireless router to my wired router?
You could get a wireless router to add to the network, but it would most likely best to do one of the following:
Get a Wireless Access Point and set it up so the D-Link router hands out IPs.
Replace the current router with a wireless router in order to simplify the set up the most.
If you want just a Wireless access point to add to your network, check your local electronics resellers, however most people would suggest a wireless router because they are easier to find and they are often cheaper in part to all the rebates that are always happening.
Yep, and you can pick them up incredibly cheaply sometimes. I got mine on sale for $70 with a $30 mail in rebate--total cost to go wireless: a big $40 (admittedly, this only 11 mbps technology, but for highspeed Internet access at 3 mbps, it's more than enough).
